SCALE.

SPECIFICATION forming part of Letters Patent No. 687,702, dated November26, 1901.

pplication filed May 6, 1899.

To @ZZ whom, it may concern:

Be it known that I, WALTER F. S'rIMPsoN, a citizen of the United States,residing at Detroit, in the county of Wayne and State of Michigan, haveinvented certain new and useful Improvements in Scales, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

The invention has general reference to coinputing-scales, and relatesparticularly to a counterbalance-weight for the scale-beam.

One of the objects of my invention is to so construct and arrange withrespect to the several scale parts a weight of the type referred to thatit may be made of considerable less size than the weights heretoforeemployed; and a further object of the invention is to so locate theweight that it will be entirely concealed from View, whereby a morefinished appearance will be given to the scale and a more compactstructure will be obtained.

To attain the objects thus enumerated, I so construct the scale that theweight will be arranged below the scale-beam, its weighing and pricemember, and likewise below the usual scale shelf or cap, whereby thebeam is brought in close proximity to said shelf with its center ofgravity at the lowest point, while the shelf or cap is utilized as ahousing to conceal and protect the weight.

The invention therefore consists in the novel construction andarrangementof the counterbalance-weight andthe peculiar arrangement andcombination of the various other parts of the scale, as will be morefully hereinafter described, and shown in the drawings, in which--Figure 1 is a sectional elevation of a scale embodying my invention.Fig. 2 is a vertical central section through a portion of the scalebeam,partly in elevation; and Fig. 3 is a section taken on line a: 0c of Fig.1.

The reference-letter A designates a counter-scale of any approved type,comprising in its construction the usual base B, the platform C, and theshelf-frame D.

E designates the usual scale-shelf, supported by the frame, and F is theusual rod connecting the scale-levers (not shown) with the beam. Uponthe scale-shelf is mounted a fulcrum-stand G, comprising spaced uprightsSerial No. 715,847. (No model.)

c, having grooved upper ends adapted to receive the knife-edge bearing eof' the scalebeam H. The beam last referred to may be, if desired, andpreferably is, a tare-beam, comprising in its construction a transversemember I, substantially parallel with the shelf, and upward-extendingarms J and K, each provided at its upper end with a bearing f, in whichis pivoted for rotary movement the weighing and price member L.

g designates a poise for the tare, and 7L is the weighing and pricepoise.

The member I of the scale-beam is formed with an offset or shoulder M,which extends downwardly between the members of the fulcrum-standard,and upon this shoulder is secured a bracket O, which carries thecounterbalance-weight P. More particularly the construction of thebracket and weight is as follows: The bracket comprises a slotted memberQ, which is secured to the shoulder M by means of a screwj and to thebeam by a screw-bolt k. The bracket at its lower end terminates in adownwardly-extending arm R, which projects through an opening S in theshelf, and extending laterally from said arm is a threaded stem T, uponwhich the weight P is adjust-ably secured.

The reference-letter U designates a link connected to the scale-beam, towhich is attached the upper end of the rod F, and V designates a stopsecured to the shelf, which limits the upward movement of said beam.

In assembling the parts the weight-carryin g bracket is adjustedvertically until the beam is evenly balanced and is then ixedly securedto the said beam in the manner before set forth. Further adjustment tobalance the beam is eected in the usual manner by adj usting laterallythe counterbalance-Weight P.

From the foregoing description of my invention it will be readilyobserved that by arranging the counterbalance-weight in the manner setforth-viz., below the beam and the shelf-the beam is brought in closeproximity to said shelf, and the center of gravity of said beam is atthe lowest point. Moreover, the weight by being arranged beneath thescale-cap, while being protected by the latter from injury, is concealedfrom View, whereby a more finished appearance is given to the scale.

ICO

What I claim as my invention isl. The combination in a counter-scale ofthe shelf or cap, a fulcrum-stand thereon, a beam fulcrumed on saidstand, and extending substantially parallel with the shelf,upwardly-extended arms on the beam, a computing and weighing membercarried in said arms, of an arm connected to the beam and extendingthrough an aperture in the cap or shelf, and the eounterbalance weightor ball adjustably secured on said arm.

2. In a weighing-scale, in combination with a fulcrum-support,the poisedbeam fulcrumed thereon, having an arm extending rigidly from the beam toa point remotely below the horizontal plane of the fulcrum at one sideof the vertical plane of the same; and a correcting-poise carried bysaid arm at such remote point, and on the side thereof toward the saidfulcrum; whereby the poise is brought underneath the fulcrum; said poisebeing adjustable horizontally within a range extending a short distanceboth sides of the vertical plane of the fulerum.

3. In a weighing-scale, in combination with the fulcrum supportingshelf, the poised beam, fulerumed above the shelf and having an armextending rigidly downward through the shelf, the shelf being aperturedfor that purpose and a correcting-poise carried by suchdownwardly-extending arm, such poise being located underneath thefulcrum and being horizontally adjustable on said arm.

4. In a weighing-scale, in combination with the fl'ilorum-supports andthe shelf on which such supports are mounted, the beam fulerumed on suchsupports and having two rigid arms extending upwardly at opposite sidesof the fulcrum, and a rigid arm extending downwardly near the fulcrum toa point below the shelf; a computing member carried on theupwardly-extending arms and eX- tending past the fulcrum; acorrecting-poise carried on the downwardly-extending arm and locatedunderneath the fulcrum and horizontally adjustable longitudinally withrespect to the beam.

5. lIn a weight and value indicating scale, a poised beam having avalue-computingchart member supported by the beam and 1ocated above thesame; the beam having an arm extending rigidly from it downward to apoint remotely below the horizontal plane of the fulcrum and one side ofthe vertical plane of the same; and a correcting-poise carried by sucharm at such remote point at the side thereof toward the vertical planeof the fulcrum, and horizontally adjustable a short distance either wayfrom said Vertical plane.

In testimony whereof I ailix my signature in presence of two witnesses.
